. CAR-COUPLING.

Specification of Letters Patent No. 23,705, dated April 19, 1859.

To all whom it may concern:

Be it known that we, H. PURLIER, J. HARLA and E. C. CHEEK, ofCincinnati, in the county of Hamilton and State of Ohio, have invented anew and useful Improvement in Car-Couplings; and we do hereby declarethat the followin is a full and clear description thereof, referencebeing had to the accompanying drawings, made to form part of thisspecification.

Our invention relates to certain improvements in car couplings, by meansof which, cars may be rendered self coupling, and which at the same timeallow the cars to be uncoupled while in motion, the said improvementsbeing described specified and represented as follows.

By reference to'the accompanying drawings, Figure 1, is a perspectiveview showing the coupling, as arranged for use, Figs. 2, and 3, aresectional views showing the arrangement and operation of the device forsecuring and releasing the clevis.

(a) is a draw bar formed with a bell shaped mouth (a) and with aninterior cavity (66) within which is arranged a tripping pin (1)) whichis secured in its proper position by means of the bolt (0), but insuchmanner that it may turn easily upon the bolt. The tripping pin (1)) isformed with a projection (cl), so that when it may be required to couplethe cars, the clevis (6) will come in contact with the pro jection (cl),and by forcing it inwardly tilt the pin (6) until the same shall assumea perpendicular position, as shown in (Fig. 2).

is a latch lever pivoted to the draw bar (a) at f) and provided with afriction roller (g), which serves as a lock to the pin (6) when thecoupling has been accomplished, and at the same time allows the lever tobe elevated, even while there is pressure upon the pin (6), so that thecars may at any time be uncoupled.

(h) is a rod pivoted to the lever (f) and arranged in such manner withreference to a lever (2') as to operate the lever (f) when it may berequired to uncouple the cars.

hen the cars are uncoupled, the tripping pin (Z), cl) will be inposition as shown by red lines in (Fig. 2), and it will readily be seenthat by forcing the clevis (6) through the mouth of the draw bar (a)against the projection the pin (6) will be tilted as before described,and the clevis secured by the lever (f) falling behind the pin; and theclevis is released, by raising the lever (f) as before described.

What we claim as our invention and desire to secure by Letters Patentis- The employment of the tripping pin (6, cl) in combination with thelatch lever (f, g) arranged and operating substantially as described forthe purposes set forth.

In testimony of which invention we have hereunto set our hands.

H. PURLIER.
